On Sunday evening (April 7), country music's brightest stars turned out with their most memorable outfits and flashiest performances for the 54th annual ACM Awards. The show brought big, high-energy performances, as well as some quieter, emotional moments that were equally powerful.

Duets were a powerful theme of the evening: The ACM Flashback series paired George Strait and Miranda Lambert together, as well teaming Luke Combs with Brooks & Dunn. Some of these performances featured unlikely pair-ups, such as Amanda Shires' contribution to Luke Combs' rendition of "Beautiful Crazy," while others felt like second nature, such as Maren Morris and Brothers Osborne's collaboration, "All My Favorite People."

Big wins, unforgettable performances and choked-up "thank you" speeches flowed a-plenty during the big night. Read on to learn about all the highlights of the 2019 ACMs!
